Explanation:
We know that
lambdaλ is wavelength("m")(m) nuν is frequency("s"^-1 (s−1 or"Hz")Hz) cc is the speed of light,2.998 xx 10^8 " m/s"2.998×108 m/s hh is Planck's constant,6.626 xx 10^-34 " J" * "s"6.626×10−34 J⋅s
We could directly use
lambda nu = cλν=c
nu = c/lambdaν=cλ
So,
The given wavelength is
lambda = 100. cancel("nm") xx ("1 m") / ("10"^9 cancel("nm") )= 10.0 ^-7 " m"
